Subject: [PATCH v3 0/2] xen/gnttab: reduce size of struct active_grant_entry
Date: Mon, 19 Sep 2022 15:57:11 +0200 [thread overview]
Message-ID: <20220919135713.16577-1-jgross@suse.com> (raw)
While looking at the grant table code I thought it should be possible
to have a smaller struct active_grant_entry. This approach should only
hit transitive grants with some negative performance effect, "normal"
grants should be not affected.

xen: add knownalive_domain_from_domid() helper
